Yeah, kinda. Actually, I gave a wrong-ish example because of more than one params, which makes the capture more difficult requiring the hairy regexp you provided above. But yes, you got the spirit of the question. Consider the more common


get '/books'
get '/books/:book_id'


I need two routes as above. Would be nice to just have one like below that does the job of both


get '/books/:book_id?'


The above is how it is implemented in CGI::Application, hence my experience with such a capability.


Thanks,
